Common Pitfalls
Translation Traps (for Russian speakers)
- False friend: Russian 'таз' correctly translates to 'pelvis' in anatomy, but also means 'basin' (bowl for washing). Ensure context is clear.
- Confusion with 'hip' (бедро) - the pelvis is the entire bony structure, not just the joint.
Common Mistakes
- Incorrect plural: 'pelvises' is acceptable, but 'pelves' (/pelviːz/) is the traditional Latin plural, often used in medicine.
- Misspelling: 'pelivs', 'pelivis'.
- Confusing 'pelvic' (adjective) with 'pelvis' (noun).
